- INV ENTOR ATTORNEY Patented May 18, 1937 UNITED STATES RATIENT'OFFICE 1 claim. (01 154%) P This invention relates to mop wringers and has for an object to provide a mop wringer which may be folded into compact form when not in use and which may be unfolded and set up over a pail or small tub to co'nveniently and quickly wring out mops of all sizes.

A further object is to provide a mop wringer including a frame and hinged supporting legs therefor, the frame being equipped with a pair of wringing rolls, one of which is adapted to be moved toward the other roll by a novel foot pedal having the ends slidably mounted in guides disposed on one pair of the supporting legs so. that the operator may exert great pressure on the movable roll when wringing out very heavy mops.

A still further object is to provide a device of this character which will be formed of a few strong, simple, and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure l is a longitudinal sectional view of a mop wringer constructed in accordance with the invention.

Figure 2 is a vertical sectional view taken on the line 22 of Figure 1.

Figure 3 is a detail sectional view taken on the line 3-3 of Figure 2.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, the device is shown to comprise a substantially rectangular frame l preferably formed of square tubing and the frame is supported at the opposite ends by pairs of legs H which may be formed of wood. Each pair of legs is hinged to the side rails |2 of the frame by means of strap hinges l3 so that the legs may be folded flat against the bottom of the frame when the device is not in use and may be unfolded to the vertical position when the device is to be used. The upper ends of the legs overlap the end rails M of the frame when the legs are rocked to operative position and are held pressed tightly against the end rails by oblique braces l5.

The braces are formed of metal straps pivotally connected together at the inner ends as shown at-|6,=andare'pivoted at the outer ends tothe side rails of the frame and to the associated legs, as shown at H. One member of each brace'is provided on the underneath face with alip l8 5 which engages the bottom 'edge-of-the mating member and holds the brace in extendedposition until the pivot I6 is manually displaced toward the adjacent hinge l3 to break the brace and permit of the associated legs being 10 folded.

A wringing roll I9 is mounted to idle on a shaft which is journaled at the ends in suitable openings in the. inner side of the tubular side rails 2. A second wringing roll 2| is fixed 5 on a shaft 22 which extends at the ends through blocks 23 which are slidably fitted in the bores of the tubular side rails l2. Helical springs 24 are secured to eyes 25 carried by the blocks and to eyes 26 carried by the adjacent end rails M of the frame and yieldably hold the blocks in position to maintain the wringing roll 2| sufliciently spaced from the wringing roll l9 so that mops of various sizes may be received between the rolls.

For moving the slidably mounted wringing 25 roll 2| toward the wringing roll I9 a pair of chains 21 are secured to eyes 28 carried by the blocks 23 and these chains are trained over guide pulleys 29 which are mounted within the bores of the side rails and thence are trained downwardly through openings 30 in the side rails and connected at the ends to a bar 3| which forms a foot pedal. The ends of the bar are slidably fitted in U-shaped guide bars 32, as best shown in Figure 3, the guide bars preferably being secured to the associated legs II by screws 33 passed through the ends of the guide bars and into the legs. An arcuate strap 34 is secured by rivets 35 or similar connectors to the foot pedal 3| and coacts with the latter in forming a pedal of suitable width against which the operator may rest the foot to depress the pedal and through the instrumentality of the chains 21. move the roll 2| toward the roll I9.

The legs are braced near their lower ends by transverse braces 36 which prevent spreading of the legs under severe conditions of service.

A crank handle 31 is formed integral with the shaft 22 of the roll 2| and forms means for manually rotating the latter after the mop is inserted between the rolls and the roll 2| advanced toward the roll l9 by depressing the foot pedal 3|. Slots 38 are formed in the side rails |2 of the frame to receive the projecting ends of the M shaft 22 of the movable roll 2| and to receivethe upper end of the crank handle 31.

In operation, the legs II are rocked downwardly and the braces l5 are then extended to hold the legs in position to maintain the frame l0 horizontal. placed underneath the frame to catch the water wrung from the mop. The mop is then inserted between the rolls |9 and 2| whereupon the operator depresses the foot pedal 3| to move the roll 2| toward the roll l9 and compress the mop between the rolls. The operator then turns the crank handle 31 to rotate the roll 2| and feed the mop through the rolls 9 and 2|. By virtue of the guides 30 being disposed on the legs II the downward pressure of the operators foot is borne by the legs I which are thus more tightly forced against the floor and the operator is thus enabled to exert great pressure upon the movable roll 2| without upsetting the mop wringer.

From the above description it is thought that the'construction and operation of the invention will be fully understood without further explanation. y

What is claimed is:

A mop wringercomprising a substantially rec- A small tub or bucket may be tangular frame having side and end bars formed of tubing, supporting legs for the frame hinged to and overlapping the end bars of the frame, a stationary wringing roll journaled in the side bars, guide blocks slidably fitted in the tubular side bars of the frame, a wringing roll journaled in said guide blocks, springs connected to one of the end bars of the frame and housed within the bores of the side bars of the frame and connected to the guide blocks for holding the last named wringing roll spaced from the stationary wringing roll, flexible connectors secured to the ,guide blocks at the opposite ends thereof from the springs, a cross bar connected to said flexible connectors, said cross bar forming a pedal, guides on a pair of the legs slidably receiving the ends of the pedal, depression of the pedal moving the guide blocks to move the associated wringing roll toward the stationary wringing roll against the tension of the springs, and a crank handle connected to one ofthe wringing rolls for rotating the roll to feed the mop between the, wringing rolls when the wringing rolls have been-moved by the pedal and the connectors to operative position to squeeze a mop between them. 25
